PLEASE NOTE: All results are preliminary and subject to change

Terms of Use:

These results are being shared as part of OHDSI's open science community efforts to characterize disease natural history of COVID-19, for the purposes of enabling collaborative research within the community. Synthesis of the results and interpretation of the findings is underway and manuscripts are being prepared. All manuscripts must be reviewed and approved by all co-authors and data partner contributors prior to submission. Until final publication, all results are to be considered preliminary and subject to change, and may only be used under the terms of use of the respective data partner contributors.

Objectives:

  1. Describe the baseline demographic, clinical characteristics, treatments and outcomes of interest among individuals tested for SARS-CoV-2 and/or diagnosed with COVID-19 overall and stratified by sex, age and specific comorbidities;
  2. Describe characteristics and outcomes of patients diagnosed/tested positive for influenza as well as patients hospitalized with influenza between September 2017 and April 2018 compared to the COVID-19 population.
